DOOR-HANGER.

Specification of Letters Patent.

Patented Apr. 2G, 1910.

To all whomc't may concern:

Be it known that I, HARRY E. BALLARD, a citizen of the United States ofAmerica, residing at Holyoke, in the county of Hampden and State ofMassachusetts, have invented new and useful Improvements inDoor-Hangers, of which the following is a specification.

This invention relates to an improvement in door-hangers andparticularly to an improvement in tracks from which sliding doors aresuspended, the object of the invention being fully set forth and claimedin the following specification.

The invention is illustrated in the acco1npanying drawings, in which,

Figure l is a side elevation of a doorhanger embodying the invention,showing it in position on a portion of a track adapted to receive it; aportion of the door suspended from the track being also shown. Fig. 2 isa cross sectional elevation in the plane of line 2-2, Fig. l, showingparticularly the relation of the wheels of the hanger to the track. Fig.3 is a perspective view of the pendent hanger arm extending from thesupporting wheel to a point below the track and constituting the supportfor the suspended door or one end thereof.

Referring now to the drawings, a indieates a track as a whole consistingof the tread portion b thereof havinga rounded upper edge, which isclamped between two metal plates c, the lower edge of the platesextending somewhat below the lower edge of the wooden tread portion bwhereby a channel, rectangular in cross section, 'is formed at theunderside of the track. The track is supported from the ceiling inbrackets d, of any desired and convenient construction.

The hanger-wheels are indicated by e, these being spaced apart by themeans of two bars f in the ends of which the axles r/ of the wheels aremounted. These wheels are grooved to run on the rounded upper edge ofthe track portion and are mounted on the axles g between the two bars f.

Midway between the axis of the wheels the pendent hanger h is locatedbeing pivotally supported between the bars f on a pin 7c in such mannerthat it may swing freely in the plane of the wheels e. This pendenthanger h has an offset m formed therein to clear the track, the lowerpart thereof, however, being located in the same vertical plane as thatend which lies between two bars ff and at 0 (which is the portion of thehanger located directly under the lower edge of the track) two planesurfaces p are provided which are parallel with the underside of thetrack and in close proximity to the lower edges of the plates c. Betweenthese surfaces ;0 is cast, or otherwise formed, a long rib g parallelwith the track and extending up into the rectangular channel in thelower edge thereof, referred to above. This rib (l is intended to lit soclosely the sides of the plates o which constitute the sides of saidchannel that it will be impossible for the hanger /zy to be oscillatedtransversely of the track far enough to bring said pendent hanger L intocontact lwith the track at any point. Furthermore, the space between thelower ends of the plates c and the plane surfaces pof the hanger is lessthan the height of the rib Q measured from the surfaces p. It istherefore impossible to remove the supportingwheels from the track,except by sliding it over a free end of the track.

In the hub 11 at the lower extremity of the hanger h is a threaded holes, whose axis is in a plane parallel with, and inclined relative to, thetrack. In this hole is located a screw t on which is rotatably supporteda couple of standards o secured to the top of the door fw. The door mayswing freely on this screw transversely of the track. I-Ieretofore, muchinconvenience has been occasioned by the fact that such swinging of thedoor on its support t, has imparted swinging movement to thehanger-wheels on the track, not infrequently causing the hangers tostrike some obstruction within the casing or boxing which incloses it,sometimes derailing it, and it is to obviate this inconvenience that thepresent invention was devised.

In the present construction, by means of the engagement of the rib withthe smooth inner faces of thc channe extending along the lower edge ofthe track, the hanger h is prevented from oscillating transversely ofthe track to any appreciable degree; and, once put in place, thehanger-arm is so interlocked with the track that its dislodgment can notbe effected, it being impossible to lift the wheels enough lo discngagetheir edoes from the track.

TVhat I claim, is

In a door-hanger, the combination with a track portion of Wood or thelike, and meta-l plates betWeen Which the track is clamped, said plateseXtendin below the track portion to constitute a c iannel; of a truckcomprising a frame, grooved Wheels mounted' tandem therein, a hanger-armsuspended from said frame and extending around the side of the track,the lower end of the arm being located in the plane of the track andhaving a proj ect-ion thereon parallel with the l0 GEO.
